The client driver\nmight also be processing data at the same time, resulting in a call to\nmhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runs\nafter mhi_unprepare_from_transfer() has torn down the channel, a panic\nwill occur due to an invalid dereference leading to a page fault.\n\nThis occurs because mhi_gen_tre() does not verify the channel state\nafter locking it. Fix this by having mhi_gen_tre() confirm the channel\nstate is valid, or return error to avoid accessing deinitialized data.\n\n[mani: added stable tag]\n\n## Affected\n\n- `linux_kernel >= 5.15.149, < 5.15.181`\n- `linux_kernel >= 6.1.76, < 6.1.135`\n- `linux_kernel >= 6.6.15, < 6.6.88`\n- `linux_kernel >= 6.7.3, < 6.12.24`\n- `linux_kernel >= 6.13, < 6.13.12`\n- `linux_kernel >= 6.14, < 6.14.3`\n- `debian_linux = 11.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.14.3`\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · updated 2026-10-16 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2025/cve-2025-23151.json)","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":230013,"id":"CVE-2025-23151","ts":1793124769884,"field":"cvss","old":"4.1","new":"7.8"},{"seq":230012,"id":"CVE-2025-23151","ts":1793124769884,"field":"severity","old":"medium","new":"high"},{"seq":223781,"id":"CVE-2025-23151","ts":1792238419359,"field":"cvss","old":"7.8","new":"4.1"},{"seq":223780,"id":"CVE-2025-23151","ts":1792238419359,"field":"severity","old":"high","new":"medium"}]}
